Preheat the oven to 190°C (375°F). Prepare a 9x5-inch loaf pan by lining and lightly greasing it. In a spacious bowl, combine all the meatloaf ingredients thoroughly until evenly incorporated. Gently press the mixture into the prepared pan, shaping it firmly into a loaf. Slide the pan into the oven and bake for 40 minutes. Meanwhile, blend the glaze ingredients in a small bowl until smooth and well mixed. After the initial baking time, remove the meatloaf from the oven and evenly coat the top with the prepared glaze. Return to the oven and continue baking for an additional 15–20 minutes. Allow the meatloaf to rest for 10 minutes before slicing to ensure it remains juicy. Serve drizzled with any collected pan juices and garnish with extra chopped parsley if desired.
